In Firefox, the mouse becomes partially unresponsive to elements in the browser and on web pages. This happens after 15-30 minutes after starting up the browser. Common symptoms include:

- Unable to drag and drop elements properly, including text after highlighting it. - Sometimes, the mouse continues to hold elements while dragging. Pressing ESC temporarily fixes this. - Dropdown menus on websites do not drop down when hoovering over them - Other items on websites don't display items when hoovering over them

I have tried:

- Different mouses, including my laptop's trackpad - A Firefox fork, namely Waterfox, but it still occurs - Limited testing with other browsers. No problem occurs - Limited testing on desktop. No problem occurs - Entering Troubleshooting Mode on Firefox - Clearing cookies and cache - Reinstall Firefox (including installing from command line instead of the snap store) - Updated Firefox - Refreshed Firefox - About:Processes doesn't show anything using more than 10-15% of CPU at any one time - Limited testing with a new Firefox profile. No problem occurs - Disabled WebGL and Hardware Acceleration.

Temporary fix: Restarting Firefox, but the problem re-occurs shortly after use.

Using Ubuntu.

Any help would be greatly appreciated.

I really want to use firefox. I really do. But firefox's memory management is making that very difficult.

I have 8GB of RAM, which really ought to be enough, but inevitably, over time, firefox will munch and munch and munch until it has consumed all of it.

And then... my system crashes. I lose work. I get angry.

Well, okay, I use linux, so after this happened a few times I stuck firefox in a systemd scope and limit it to 90% of the memory of my system. At first, that didn't work because firefox would simply eat into the pagefile, until it had consumed all of it (or as much as I entitled it to), at which point firefox would desperately try to do.... something, very frantically, which would lock the CPU usage to 100%, again bringing down the system. So I limit its RAM and prohibit it from using the pagefile, and now, it's just firefox that dies.

....

But, really, that's still a problem. I still have emails partially written, forms filled out, work is still lost. Is it really so abhorrent to take out the trash that you'd rather just commit suicide instead? I say take out the trash, because firefox will restart, reload those very same tabs, and carry on with a fraction of the memory usage. Something's been dropped, and it wasn't important (well, other than the content of that email I've been composing for the last half hour).

So. If I'm going to continue using firefox, which I would very much like to do, there needs to be some way for it to gracefully say to the user: "I've run out of available memory. I'm going to have to..." (for example) 1. perform garbage collection (do whatever 'minimize memory use' seems to do... which is not much, but something that really ought to be the default action in this situation) 2. clear the buffer of some videos being played, or some cached results or something, i dunno. 3. gracefully stop loading the current tab, or process, or whatever, and say to the user "I've run out of resources to continue. Please choose one or more tabs to close in order to continue"

Then, at least, I can sacrifice my background music tab, or something else unimportant, to buy enough time to copy that email into notepad, submit that form, or just run 'minimize memory usage', and be able to carry on.

Hello,

I see with windows Firefox version 118 a TLS extension id 65037 on every client hello handshake containing a bunch of data. Does somebody know what this extension is used for? I couldn't find anything about this on the web or in the firefox docs / release notes. Other browser (chrome / edge) don't have this extension in use.

Thanks

Hola. Mi ordenador tiene Debian 12. Utilizo Firefox 118, instalado a través de Flatpak. El problema que tengo en algunas páginas es que veo las fuentes pixeladas y la impresión es muy defectuosa, hasta el punto de no entender lo que aparece escrito. Esto sólo pasa en algunas páginas.

Si descargo directamente Firefox desde la página de Mozilla y abro la paǵina con una configuración limpia del navegador, las fuentes se ven correctamente; sin embargo, si sincronizo los datos de usuario, instalándose los datos, extensiones y demás las fuentes en determinadas páginas se ven mal.

Desactivé las extensiones pero el problema no se resuelve. Desde una instalación limpia de Firefox instalé una a una las extensiones y complementos, pero no logré reproducir el problema. Borré incluso la caché del navegador, pero nada. Y también sincronicé los datos de usuario en una instalación de Firefox en Fedora, pero el resultado es también negativo.

Alguna idea?

Gracias.

Hi,

I am using Linux Mint 20.3, 64-bit and both Firefox and Chrome are not loading images for me on certain websites (i.e. okcupid). In particular, I am noticing that images will actually load for a split second and then disappear moments later.

I've tried disabling my adblockers, deleting my cookies and cache, running Firefox in Troubleshoot and Diagnose mode, running Chrome in Incognito mode, and evening uninstalling and reinstalling Firefox. Still the issue persists.

I followed the advice here: https://support.mozilla.org/en-US/kb/fi ... s-not-show

Any advice or suggestions would be most welcome.

Thanks, Chris

Hi, when using the --search option with firefox in the command line a new window is opened regardless of whether the 'open in new tab instead of new window' option is checked in settings or whether the --new-instance option is added.

Is there a way around this? I'm trying to have a command that would make a search in a new tab of the current instance of Firefox.

Thanks.

When I open a website where there is a document upload feature and I want to upload a document but when I click the button to upload a document Firefox can't respond, I've tried several methods such as deleting cache, even reinstalling but I still encounter this problem.

I can't add images to this report because of this problem

Thank you

I have a problem with Firefox not maintaining granted permissions which forces having to re-grant them, re-authorize/signin etc each time (several times a day). The problem exist on several sites (I think they're related, please correct me if not). eg google workspace suite; I'm using gmail in browser, with Calendar, Drive, Voice, and other elements. Having logged in to gmail (which always forces 2fa even though I check "remember this device"), using the other functions of workspace should be authorized, but if I go to say a folder in Drive, or try to create a Calendar event from an email, a new tab opens and I'm forced to sign-in again (with 2fa). All the google addresses I use are in the "allowed" section of Firefox settings, their cookies saved as exceptions for filtering and saved on exit, and allowed in cross-site filtering. I can't think of anything else to do that would prevent having to sign-in all the time. Similarly with other secure sites such as financial institutions, despite having them bookmarked, cookies allowed, checking "remember this site" etc, every instance has to be re-authorized, re-signed in with 2Fa etc. I only ever use the same laptop and smart phone so it doesn't make sense that neither of these devices are ever recognized. I even get email notifications "detected a new signin on an unknown device" etc. and this happens across sessions, before hibernation or shutdown. How do I get premissions to persist?

Thunderbird: Folder with 119 message, need to send all 119 messages to an e-mail from Local box called "Fraudfiles". I can not see any way to do this in Thunderbird e-mail.

This happens at random intervals, mostly when firefox is being left idle.

Since it starts >1000 threads, it easily fills ram and swap, then get killed by OOM killer. Hence no crash reports.

I'll upload a gist with OOM details from dmesg and journalctl, if there is a way to get debug info for this, please let me know.

When I select in Settings>Privacy & Security>History, that a history should never be saved and close the Settings tab, the next time I go to Settings, the option is replaced by the setting, that saves a history according to customisation and there's a check mark to always use the Private Mode. Apparently Firefox doesn't keep or save the setting. I learned from https://support.mozilla.org/de/kb/privater-modus that saving a history according to customisation with the option to always use the Private Mode enabled, is the same as never saving a history, nevertheless it should be possible to keep the setting (as the setting exists). How can I solve the problem?

After installing version 118, Firefox does not automatically explain the pages.I have to go out in the settings and choose the language of the translation every time. The problem occurs after the browser is synchronized. MX Linux system.

With a recent update of Firefox Developer Edition to version 117.0b9 i keep getting extremely annoying popups on all sites, asking me if I want to translate stuff.

I don't want to store unnecessary settings in my browser, related to exceptions to websites/languages that I want vs. does not want to translate.

I want to completely disable translations, globally. Forever. Two questions:

- Why there is no "disable translations globally" checkbox in the newly added popup? - Is there an about:config hack to do disable translations globally, for all languages, for all websites, and forever?

thanks in advance

while performing a download, "com.android.phone has stopped" apears, the signal strenght indicator in the upper right restarts(disappears, reappears with the 4G mark, the mark disappears and the indicator works after), after that the phone service and the phone app work normally. the download finishes normally.

using motorola e7 plus, android 10

tried restarting the phone, deleting cash and data of phone app, deleting cash of firefox

tried downloading using google chrome, all work normally.

it is possible that the issue started happening after I updated firefox but It's possible that it was happening before too.

There is no gear icon when I open a new tab. and my thumbnails are missing. Tried the solution here Right clicking does not give the option to restore defaults. value of browser.newtabpage.enabled is true. changing it to false did not change anything, neither did changing it back again.

I want Firefox on my action (button press or keyboard shortcut) run shell script or program of my choice and giving it as parameter the url of the actual web page I'm seeing.

Is it even possible?

i cannot get the mic and camera to show in firefox any and chromebook versions including full desktop version linux, all settings enabled firefox.

on option in sttings , let website ask to use camera or mic,  hello id like voice search and vid conf but i cant enable it, works fine on mobile phone. so the user cannot use his computer in those 2 features unless a website requests it, what a stupid setting really

I am using Firefox 115.3 on Debian 12.1. I have numerous tasks which require the use of my web browser and have allocated a different virtual desktop for each. This means that my browser session typically has several dozen tabs open in numerous windows at one time. Under normal circumstances, this works just fine (and is a testament to the engineering that has gone into this browser).

My issue is that Firefox renders my machine virtually unusable for a few minutes each time I restart my desktop session due to focus stealing. When I open the browser, several dozen windows pop up (as expected) and relocate to their correct virtual desktops (as expected); however, as the windows begin to load, the most recently active Firefox window steals focus repeatedly. If I am, for instance, in the process of typing my password into my desktop e-mail client, a Firefox window may steal focus from the password dialog. In practice, this focus steal happens once every few seconds for several minutes.

I would prefer that Firefox would not steal focus while restoring a session. Does anyone have any suggestions for correcting this issue?

Same as the question.

The display shows some icons on the last tabs I opened but it seems only some basic website layout is loaded but all the details are gone. Like text, button borders, even the exit, fullscreen and minimize buttons. I have seen that this has been an issue for quite some time before so I am looking if there is a fix or a workaround. I have and Nvidia graphics card and drivers if that means anything. And my swap file is 20 GB and my RAM is 16 so the space shouldn't be a problem. It gets fixed when I turn off Firefox but not when I refresh tabs.

The crazy thing is that when I take a screenshot inside firefox (with firefox integrated screenshot option, like when I press right click and then take screenshot. I can see the text so it seems like it is a display problem but this only happens with firefox and not other apps.

Appreciate all the help. I will ask of ubuntu formums next if I don't find a solution here.

Thank you all for reading and answering!

I'm encountering consistent video playback issues on Firefox while running Fedora 38. The error message I receive when attempting to play videos from certain sites, notably LinkedIn and Twitter (now X), is:

• The media playback was aborted due to a corruption problem or because the media used features your browser did not support.*

Furthermore, when examining Firefox's console while attempting to play a video, I observed the following error:

• [Child 5999, MediaDecoderStateMachine #1] WARNING: Decoder=7fdb3c55a100 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - mozilla::MediaResult mozilla::FFmpegDataDecoder<60>::InitDecoder(AVDictionary**): Couldn't open avcodec: file /builddir/build/BUILD/firefox-118.0/dom/media/MediaDecoderStateMachineBase.cpp:166*

Steps to Reproduce: 1. Navigate to LinkedIn or X (previously Twitter). 2. Attempt to play any video content. 3. Observe the aforementioned error.

Additional Details: - OS: Fedora 38 - Firefox version: Initially 117.0.1, then updated to 118, both 64-bit. - This issue does not occur on Google Chrome on the same system. - I have attempted the following troubleshooting steps without success:

 1. Updated Firefox to the latest version.
 2. Enabled DRM content.
 3. Booted Firefox in Safe Mode.
 4. Disabled hardware acceleration.
 5. Cleared cache and cookies.
 6. Used a Flatpak version of Firefox.

This issue has significantly impacted my user experience, and I hope to find a resolution soon. Any assistance or guidance would be greatly appreciated.

Thank you!
